# There is an interesting problem with interaction between ACL_WRITE_ACL
# and SUID/SGID bits.  In case user does have ACL_WRITE_ACL, but is not
# a file owner, Solaris does the following:
# 1. Setting SUID fails with EPERM.
# 2. Setting SGID succeeds, but mode is not changed.
# 3. Modifying ACL does not clear SUID nor SGID bits.
# 4. Writing the file does clear both SUID and SGID bits.
#
# What we are doing is the following:
# 1. Setting SUID or SGID fails with EPERM.
# 2. Modifying ACL does not clear SUID nor SGID bits.
# 3. Writing the file does clear both SUID and SGID bits.
#
# Check whether user 65534 is denied to write mode with SUID bit.
